If I have a credit-card number that I wish to process, then I don't want that being printed to the screen, to a log-file, saved to disk, and definitely not sent out in an e-mail.

Then don't do any of those things. There isn't any safeguard for programmer error. It happens all the time.

Passwords, encryption keys, and other sensitive data in many systems can be marked as restricted, providing an extra safeguard against them inadventantly being revealed.

I couldn't help but think about Java's private, protected and private protected (or is it protected private?) safeguards. By default, Perl 6 will make class variables private, which I think is a good thing.
